KTB21122021-12-01. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY:SLAVE CYLINDER; STRUCTURE. On affected motorcycles there is a possibility that the bellow style gasket can be damaged caused by deviations during assembly. Damage to the bellow gasket may affect the function of the clutch slave cylinder. This could result in the rider noticing a change in shifting behavior and the clutch becoming inoperable to the point where the clutch will not disengage when the clutch lever is pulled in. To ensure the highest level of safety, performance, reliability and customer satisfaction, it is necessary to replace the clutch slave cylinder on all affected motorcycles that have a bellow style gasket clutch slave cylinder mounted (Fig. 1).
TB18142020-09-30. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL. During the course of quality controls, KTM North America, Inc. has found that the tolerances between the decompression weight and decompression screw (marked in blue) are not in specification on select 2018 690 Duke model motorcycles. These auto-decompression system components must be replaced to prevent premature wear.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
